All 95 octane petrol in France has been E10 for a while now. When I took delivery of my Mog, the guys at Morgan France recommended that although the motor would run fine on 95 octane E10 petrol, I should always use the 98 octane because of the way the ethanol soaks up water it could lead to corrosion issues in the petrol tank. So that's what I've done.
